Vali Tech® Downhole Filter
The CleanWell® Vali Tech® downhole filter tool is designed to validate and provide a mechanical alternative to collect solid contaminates remaining in vertical or deviated wellbores. The robust design of the filter tube helps eliminate wire-wrapped screen concerns while allowing for improved operating specifications.
The Vali Tech filter features include a fluid interrupter sleeve (FIS) which provides a protected, redundant wiper diverter system designed to mitigate tearing, ripping or damage concerns. The upper location of the FIS prevents potential debris loss.
The innovative modulating valve allows fluid bypass should the collection chamber become full and helps prevent swabbing concerns. This system is also designed to eliminate the need for other ball-drop bypass valves simplifying designs.
The Vali Tech filter is ideal for highly deviated wellbores where solids tend to settle on the low side or when unfavorable hydraulics are present. The tool can be run as a standalone device for specialty intervention runs or integrated into a single-trip system in combination with other wellbore cleaning tools.
